I understand, but what if you establish a 10/20 year increasing taxation scheme. Plus some decreasing tax incentive to sell residential property.

You tell people: You have 20 years to sell your second/third residential properties, even at a good tax premium. But in 20 years you MUST have sold or you Will pay lots.of.taxes.

Edit: anyhow... I dont pretend to try to solve this complex issue in a couple of HN comments. It's just a general sentiment I have that the.only way to remove speculation from residential property is by government mandate.

I'm all for this. And I am "part of the problem " as I own 2 houses in 2 different states, and rent one at a freaking high rent price, because the market in that area is crazy.
